Successful management of bulky osseous metastasis of renal cell carcinoma with selective arterial embolization and radiofrequency ablation: a case report

The case of a 64-year-old male patient who presented with a bulky osseous tumor metastasis from renal cell carcinoma is reported. The metastatic lesion extended from the acetabulum of the left iliac bone into the iliosacral joint. Treatment plan included selective arterial embolization followed by transdermal radiofrequency ablation, followed by consolidation irradiation. This sequence resulted in considerable necrosis of the bulk of the tumor and creation of a large tissue deficit, which healed over the period of several months despite anti-angiogenetic systematic treatment. The patient remains in good state of health, 20 months after the procedure. This case illustrates the usefulness of the embolization-ablation sequence in controlling large osseus metastasis.
